Groundwater is a vital resource for many people in Iowa. The quality of groundwater for drinking, agricultural, or commercial uses is a concern not only for Iowa’s Ambient Water Monitoring Program, but also for all the citizens of Iowa who rely on these resources. For approximately 79 percent of Iowans, the water in their drinking glass is groundwater. The average Iowan uses nearly 1,100 gallons of water each day if indirect sources such as manufacturing of products, food production and energy generation are included. Individually, Iowans use approximately 100 gallons per day for drinking and other household uses.
